7 '0 all whom it may concern:

Be it known that I, EDWARD J. WILLMAN, Sn, citizen of the United States of America, residing at Louisville, in the county .o'f'Jefferson and State of 'Kentucky,'-have invent- I ed new and useful Improvements in Valves,

of which the following is a specification.

This invention relates to improvements in valves especially adapted for use in flush tanks and has for an object the provision of a valve which is seated by a movement in the direction of the water entering the valve and opened against the action of the water.

Another object is the provision of a valve of this character whose operation is controlled by the depth of water in the tank, so that although the valve closes in the direction of the incoming water and closes with the water pressure, its operation depends entirely upon the amount of water in the tank.

' Another object is the provision of a valve which embodies the above and other objects,

. in addition to its simple construction and positive method of operation.

Other objects and advantages of the in vent-ion will appear as the following description is read in connection with the accompanying drawings.

In the drawings Pg. 1' is a front elevation of the valve showing a fragmentary portion of a flush tank and the manner of securing the valve in position.

Fig. 2 is a vertical longitudinal section taken centrally of the valve and showing the same in closed position.

Fig. 3 is a like view with the valve open.

Fig. 4 is a plan View of the valve.

Referring specifically to the drawings, wherein like characters of reference denote corresponding parts, the reference character 10 indicates the bottom of a flush tank to which the valve is applied. The valve which is indicated at 11 is designed to control the admission of water to the tank and includes a valve casing made up of separate sections 12 and 13. These sections are cylindrical in is provided with a collar 16 spaced from the end. This end is also threaded as indicated at 17 and is designed-to be inserted through an opening in the bottom 10 of the tank and to "be secured "inpositio'n by a lock nut 18. The pipe section" 19 maybe suitably connecte'd'tothe extremity of the section 13 for connection with asuitable water supply.

The lower end of the upper section 12 is provided upon the extremity thereof with a valve seat 20 and operating against this seat is a valve 21, the latter being removably secured upon the lower end of a valve stem 22, being clamped thereon between a flange 23 and the lock nut 24. The stem 22 extends upward through the top of the upper casing section 12 and carries at its upper end a toothed rack 25. The teeth of this rack are engaged by the teeth 26 of a segment 27. This segment is secured upon a shaft 28, by means of'a set screw 29 and the said shaft is mounted in bearing openings 80 which are provided in spaced arms 31 extending from the upper end of the upper casing section 12, the said arms being offset from the casing.

In order to guide the valve stem 22 in its movement, the rack has extending longitudinally upon opposite sides thereof flanges 33 which provide grooves for the re ception of guides 32 extending upwardly from the upper end of the casing section 12. The end of the shaft 28 is provided with an arm 34 which carries at its free end a float 35.

In the operation of the invention, when the water in the tank is being discharged, the water lowering in the tank will cause the lowering of the float 35 to rock the shaft 28 in its bearings. This movement will, through the toothed segment 27 and the rack 25 impart a downward movement to the valve 21 and open said valve against the pressure of the incoming water. The water will then pass from the valve into the tank through an outlet pipe 36. After the water in the tank has reached a predetermined maximum level, the valve 21 will be again seated due to the rising of the float 35 and the movement of the shaft 28 as the water enters the tank. The valve casing is further provided with an after fill tube 37.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claims.

Having described the invention what is claimed is l. A valve comprising a casing, a valve movable therein, a stem fixed to the valve and projecting outwardly through the casing, a rack on the projecting portion of the stem, said rack being provided with opposite longitudinally extending grooves, a pair of guides carried by the casing and disposed in said grooves and means for engaging the rack to actuate the valve.

2. A valve comprising upper and lower casing sections detach-ably held together and divided by a transversely extending partition wall integral with the lower end of the upper section, said wall being formed with a central aperture surrounded by a downwardly facing valve seat, a valve engaging said seat and provided with a stem projecting upwardly through the top wall of the upper casing section, a rack carried by the projecting portion of the stem, a pair of offset brackets carried by the upper casing sections, a rotatable sha'ft journaled in said brackets, a gear segment fixed to the shaft between the brackets for engaging said rack, an arm fixed to one end of the shaft and a float carried by the said arm.

In testimony whereof I afiix my signature.
